> I can't use port 80 because some other application used the port 80.That's why I asked you to give the result s an integrated test as tools in wampserver.

Port 80 is reserved for the http protocol and it is not up to Apache to change port if an application uses this port. It is up to the application to change port or not to be used.Depending on the test results, we can tell you what to do so that port 80 is assigned to Apache, which must always be the case.
